loading saved flights

Since ,I have had the tutorial #2 flights added to my saved flights It has slowed down my loading speed to a point where it takes forever to load, such as the INNSBRK approach, I know this is not a problem with the program or pmdg, Its a matter of proccesing speed, however I think my best chance for some help would be with you guys . Is there something I can do to speed up the the loading of the scenery other than deleting 90% of my saved flights ? I have a dual core e8400 w/ 8gbof ram, and no add on scenery, I'm not very good w/ computers,so if you try and explain it to me you'll have to go step by step, Thank's for any help. I don't have a lot of flights saved, only the #2 tutorial flights and one other is on there.
